Contralateral transplantation of a finger for restoration of thumb function.

Transplantation of a finger from the contralateral hand for thumb reconstruction is seldom done because of possible psychological problems for the patient. We present two cases in which a previously damaged index finger of the contralateral hand was transplanted. In both patients the metacarpophalangeal joint of the index finger replaced that of the thumb. A powerful pinch to the fingers was achieved and the appearance of both the donor and the recipient hands was considerably improved.
